Calving rate: The number of calves Born alive in any year expressed as a percentage of the number of females let to the Bull in the previous year.

产犊率：指一年所产活犊数量与前一年参加交配的母牛数量之比。

In the first 32 days after calving the number of macrophage in uterus tissue increased greatly, lysosome and mitochondrion in these cells increased too.

产后1～32d之间，子宫组织内巨噬细胞数量增多，其胞质内溶酶体、线粒体等细胞器增多；

In addition, the relationships among sexes of calves, calving number and infestation rate and mixed-infestation of the other parasites were described in detail.

轻度感染的占阳性数的18.18%。此外，本文还对犊牛不同性别、母牛胎次与感染率的关系以及与其他寄生虫混合感染等情况进行了详细的记述。

The correlation values between maternal additive genetic effects of growth traits and calving date were from 0.01 to 0.20.Significant influences of herd and sire on almost all growth traits were found;

母体加性遗传效应与配种-产犊天数的相关值为0.01～0.20，两者间没有什么必然的关联。公牛效应是影响生长性状的重要因素。

14 cows were divided into the control and treatment groups on the basis of parity and expecting calving date.

本实验选用14头年龄、胎次、产奶量、乳成分基本一致的奶牛，分为对照组和试验组。

50 cows were divided into experiment group and control group according to milk yield, calving date and lactation.

实验选用了50头奶牛，根据产奶量、泌乳天数和胎次相近的原则分为试验组和对照组。
